I didn't buy a car, why did I receive the verification code of PICC auto insurance?

The mobile phone number is wrong. When buying insurance, the car buyer will first receive the verification code with the mobile phone number to verify whether the entered mobile phone number is normal and ensure the follow-up service. The car buyer entered the wrong mobile phone number and sent it to someone else's mobile phone number, so I didn't buy a car and received the verification code of PICC auto insurance because the car buyer entered the wrong mobile phone number. The verification code is a public automatic program, which is used to distinguish whether the user is a computer or a person.
